5. If the average speed of Train A increases by 10% then when will it reach to its destination?

(a) 7:45 am

(b) 9:45 am

(c) 8:45 am

(d) 10:45 am

(e) 11:45 am

(c) 8:45 am

If the average speed of train A increases by 10%
then its new speed = 73.84 × 110/100
= 81.22 kmph
Time taken by train A during the journey = 1280/81.22 = 15.75 hours = 15 hours 45 minutes
The time when the train will reach its destination = 5 pm + 15 hours 45 minutes = 8:45 am

7. The total sales of all the seven years is the maximum for which battery?

(a) 4AH

(b) 7AH

(c) 32AH

(d) 35AH

(e) None of these

(c) 32AH

The total sales (in thousands) of all the seven years for various batteries are:

For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676

For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694

For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901

For 35AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601

For 55AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.

Clearly, sales are maximum in case of 32AH batteries.
